BLACKSMITHS HAMMER.

SPECIFICATION forming part of Letters Patent No. 273,793, dated March13, 1883.

Application filed October 12, 1882.

To all whom it may concern:

Be it known that I, ANDREW ANDERSON, a citizen of the United States,residing at Elizabeth, in the county of Union and State of New Jersey,have invented certain new and useful Improvementsin Blacksmiths Hammersand Anvils; and I do declare the following to be a tull, ch-ar, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresofreference marked thereon,which form a part of this specification.

This invention has relation to improvements in trip-hammers where it isdesirable for the operator to have the use of both his hands; and itconsists in the construction, combination, and arrangement of theseveral parts, as will be hereinafter fully described, and specificallypointed out in the claim.

In the drawings, Figure l is a side view; and Fig. 2 is a detached planview, showing the top of the spring.

a is a stand provided with top cross-bar, a, and furnishing a suitablesnpportfor the spring and hammer, hereinafter described.

I) is a helical spring, the several coils of which are arranged in thesame plane. The end of the smallest coil or the inner end of this springis made fast to the top bar a, as shown, while its outer end is madefast to the end of the hammer c.

d is an anvil arranged in position to receive the blows of the hammer c.

e is a chain having one end connected to the handle 0 near the joint ofthe latter with the coil-spring b, and its other end extended down andmade fast to a lever,f, which has one end pivoted in the stand a and itsopposite end extended in rear of the anvil.

My invention is particularly useful to blacksmiths, and is intended tosave the expense of a helper to swing the sledge.

In operation, the smith stands in position behind or to one side of theanvil, with one foot on the lever f, and holds his work in the tongswith one and his hand-hammer with the other hand, and alternatelystrikes with the hand-hammer and depresses the lever f with (No model.)

his foot, thus striking with the sledge. The sledge, having its endsecured on the end of the spring and not being pivoted on a fixedbearing, is thrown in a motion almost exactly like that given by hand.

While I regard my invention as peculiarly useful to blacksmiths, I donot desire to confine myself to its use by them, as it will beunderstood it would be of great advantage to locksmiths and jewelers,where it is desirable for them to grasp the work with both hands. Insuch cases frequently the work is held in the hands and not put on ananvil or similar bed to be hammered, the hammering often consisting oflight taps with a small hammer. The inner end of the helical spring insuch cases could be made last to a support mounted on the work table orbench.

Where so desired, the chain or cord 6 might be secured at ditl'erentpoints along the handie 0, so as to give different swings to the hammer;but for ordinary use I find it Well to secure the chain to the hammerclose to its joint with the spring b.

I am aware that it is not new in operating trip-hammers or olivers toemploy a helicalspring which has its outer or eccentric end made fast toa rigid support and its inner or central end secured to a shaft rotatingin fixed hearings, to which shaft. the helve of the hammer is made last;and I do not claim such coir struction as my invention.

Having thus described my invention, what I claim,and desire to secure byLetters Patent, 1s

In a trip-hammer or oliver, the combination of a support, a helicalspring having its inner or central end made fast to the support and itsouter or eccentric end detached and swinging freely, a helve or handleadapted to carry a hammer on one end, and having its other end made fastto the eccentric or swinging end of the helical spring, and means foroperating the hammer, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

ANDREW ANDERSON.
